2024年8月12日 · What is a pontine stroke? A pontine stroke (infarction) happens when there’s a blood flow blockage to a part of your brainstem called the pons. It’s a type of ischemic stroke. The blockage may be sudden (acute) or develop over time (chronic). Cleveland Clinic is a non-profit academic medical center.

2024年10月20日 · Pontine strokes happen when the blood supply to the pons region of the brainstem is cut off. They can be ischemic strokes, which occur when a blood clot blocks flow, or hemorrhagic strokes, which occur when a blood vessel bursts.

2023年5月29日 · Pons is the largest component of the brainstem located distal to the midbrain and proximal to the medulla oblongata. Any obstruction of blood supply to the pons, whether acute or chronic, causes pontine infarction, a type of ischemic stroke.

2024年4月18日 · A pontine stroke is a stroke that develops in the blood vessels that supply your pons, a structure in the brainstem that controls unconscious functions like the sleep-wake cycle and coordinating...

2022年6月28日 · When the disruption is caused by a blood clot in particular, it’s referred to as a pontine infarction or pontine infarct. As signals responsible for the body’s motor control flow through the pons, a common effect of a pontine stroke is hemiparesis, or …

Most of the pons is supplied by the pontine arteries, which arise from the basilar artery. A smaller portion of the pons is supplied by the anterior and posterior inferior cerebellar arteries.

2024年9月30日 · A pontine stroke occurs when blood flow to the pons is disrupted, either due to a blockage (ischemic stroke) or a bleed (hemorrhagic stroke). Ischemic strokes in the pons are the more common of the two, accounting for about 80% of all pontine strokes.

2019年2月6日 · A pontine cerebrovascular accident (also known as a pontine CVA or pontine stroke) is a type of ischemic stroke that affects the pons region of the brain stem. A pontine stroke can be particularly devastating and may lead to paralysis and the rare condition known as Locked-in Syndrome (LiS).

2023年2月23日 · A pontine stroke is a serious health condition that requires immediate medical attention. Disrupted blood flow to the brain stem causes a pontine stroke. Symptoms can range from difficulty speaking to dizziness and balance problems.

2025年1月10日 · Pontine strokes are medical emergencies that require immediate treatment. The highest priority is restoring blood flow to the pons, which can be done through medication or a procedure called a mechanical thrombectomy.
